It's that time of the year: Just about every social site will be sharing the big stories that happened on their services in 2013. And Twitter is no different.

The social company has published a 2013 retrospective, allowing folks to check out some of the biggest stories that hit its network over the last year. The #2013 pane looks at the hottest topics each month, like the Academy Awards in February and the Boston Marathon bombings in April. Each month includes fast facts and some of the most popular tweets around a given subject. On the Boston Marathon bombings, Twitter says 27 million tweets were published discussing the bombings and the manhunt.
